Apache Cassandra is a free and open-source distributed wide column store NoSQL database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure.
#What is Cassandra?
Cassandra is a distributed NoSQL database management system designed to handle large amounts of data across commodity servers while providing high availability and fault tolerance. It was initially developed by Facebook and is now maintained by the Apache Software Foundation.
#Cassandra Key Features
Here are some of the most recognizable features of Cassandra:
- Distributed architecture: Cassandra is designed to run on a cluster of commodity hardware, allowing for easy scaling and fault tolerance.
- Column-family data model: Cassandra uses a column-family data model, which allows for dynamic column addition and removal without modifying the underlying schema.
- Highly available: Cassandra is designed to provide high availability and fault tolerance, with no single point of failure.
- Tunable consistency: Cassandra provides tunable consistency, allowing users to choose the level of consistency they require for a particular operation.
- Support for ACID transactions: Cassandra provides support for ACID transactions, allowing for atomicity, consistency, isolation, and durability.
- Linear scalability: Cassandra’s distributed architecture allows for linear scalability, meaning that performance increases as nodes are added to the cluster.
Here are some of the use cases for Cassandra:
- Large-scale web applications: Cassandra is commonly used in web applications that require a high degree of scalability, such as social networks and online gaming platforms.
- Internet of Things (IoT) applications: Cassandra is well-suited for IoT applications, which typically generate large amounts of data that need to be stored and analyzed in real-time.
- Time-series data: Cassandra is frequently used for storing time-series data, such as financial data, sensor data, and log data.
